GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent No. 465,220, dated December15, 1891.

Application filed $eptember 28, 1891. Serial No.407,038. (No model.)

To all whom, it may concern.-

Be it known that we, FERDINAND STEINKE and GEORGE PROPS'I, citizens ofthe United States, residing at Horicon, in the county of Dodge and Stateof Wisconsin, have invented certain new and useful Improvements inGrain-Drills, of which the following is a specification.

Our invention relates to grain-drills; and it consists in a novelconstruction of the shoe or furrow-opener.

In the drawings, Figure 1 is a perspective view of our improved shoe;Fig. 2, a side view with one of the side plates removed; Fig. 3, avertical transverse sectional view on the line a: so of Fig. 2; andFigs. 4, 5, 6, and 7 show the V invention applied to a furrow-openerhaving 1 and 2.

the ordinary cutting-disk.

A indicates the feed-spout, having on its front face a forwardly-projecting arm a, which latter is in turn provided with adownwardlyprojecting lug b, as shown in Figs. 2 and 3.

B B indicate two plates connected at their forward ends by a bolt 0, bypreference the same bolt which secures the draw-bar or brace-bar C. Attheir rear ends these plates are held apart by the lug b, as shown inFig. 3, which they firmly embrace and to which they are rigidly unitedby means of a bolt, screw, or rivet d, extending transversely throughthe lug and plates, as shown in Figs. Upon reference to Fig. 2 it willalso be observed that the rear end e of the spout A projects downwardbetween the rear ends of the plates B B, thereby forming a shortextension of the'spout and assisting in the bracing of the parts.

D indicates a toe or wedge which fits between the lower edges of theplates, the said wedge being V-shaped in cross-section, as shown in Fig.3. This toe or wedge is provided along its upper edge with a lug, rib,or flange f, or it may be merely a series of short lugs, which serve asa spacing-block for the plates B B, which embrace it upon oppositefaces, and to which it is secured bybolts, rivets, or screws 9 g, which,as shown in Figs. 1 and 2, pass transversely through the plates and theinterposed lug of the toe. In order to further secure the toe or wedgein place, we provide a bolt h, secured in any suitable manner at itslower end to the lug or flange f and projecting upward through the arm aand lug b, where it is provided with a nut 1, as shown in Figs. 1, 2,and 3. In advance of this bolt h is a second bolt j, secured at itslower end to the toe or wedge and extending upward above the plates,where it passes through or is provided with a cap or block K, fittingupon the upper edges of the plates and held in place thereon by means ofa nut l, as shown in Figs. 1 and 2.

To relieve the bolts, screws, or rivets g g of the strain to which theywould be subjected by the dragging of the shoe through the ground, weform on the toe or wedge a transverse lug or projection m, which,engaging a corresponding seat in the lower edge of the plates, preventsany longitudinal movement of the toe relatively to the plates and takesup the strain that would otherwise come upon the rivets g. Thisarrangement may, but not with such good results, be reversed that is tosay, the lug or projection may be formed on the plates and the socket onthe toe or wedge. 7

Upon reference to Figs. 4 to 7, it will be seen that the invention canwithout materlal change be applied to those shoes or furrowopenersemploying a rotatable disk to run in advance of the too or wedge. Owingto the presence of the disk, which is journaled between the forward endsof the plates, the too or Wedge is made much shorter than under theprior arrangement. This shortening of the toe or wedge enables us todispense with the transverse lug m and the bolt-j, with its cap and nut;but otherwise the construction and arrangement correspond with thatpreviously'described and shown.

From the foregoing description it will be seen that the toe or Wedge maybe readily removed for sharpening, &c., and that any of the parts may becheaply and readily re placed when broken.

Having thus described our inventiomwhat we claim is- 1. In combinationwith spout A, having arm a and lug b, the plates B B, embracing the lugand secured thereto, and the toe or Wedge secured to the plates.

2. In combination with spout A, having arm a and lug b, the wedge or toehaving lug or flange f, the plates embracing the lugs 12 and f, andfastenings for uniting the parts.

3. In combination with spout A, having arm a and lug b, the plates B B,the toe or wedge D, and the bolt h, secured at its lower end to the toeor wedge and passing up through the lug and arm.

4. In combination with spout A, having a spacing lug b and rear downwardextension e, a toe or wedge D, and the side plates B B.

5. In combination with aspoutA and plates B B, the toe or wedge D,having a transverse lug m to engage the plates and relieve the fasteningdevices of undue strain.

6. In a shoe for drills, &c., the combination,

with a spout, of plates embracing the side faces thereof, a toe or wedgeprojecting up between the plates at their lower edges, and suitablefastening devices for uniting the parts. I

7. In combination with spout A, toe or wedge D, and side plates B B, thebolt j, hav-
